26 Claims. 1

This invention relates to printing registers and, more particularly, to transaction printing registers used in toll checking systems and the like.

In modern multi-lane toll collection stations, it is usual to provide centrally located, automatic printing registers using electrical pulse operated counting relays to print periodically such pertinent information as total forward and backward axle counts, the number of transactions for each of the various toll tariif classifications, the operators identification number, etc. It is usual, in such installations, to have an electric clock connected with the printing register so that prints are made periodically, hourly, for instance. It is also usual to have additional prints automatically taken when a toll collector opens and closes a collection lane in a tour of duty in order that a complete record will be made of the transactions for which he is responsible.

In such a system, since there are many individual transactions between the automatic hourly prints, it is difilcult, if not impossible, to trace the origin of toll collection errors.

Accordingly, it is an object of this invention to provide a transaction printer adapted to be connected, selectively, by a switch at said printer, or at a position remote from said printer, to any one of a plurality of toll collection lanes in order that a detailed record of the individual transactions of the operator in the lane selected can be obtained.

It is a further object of this invention to provide, in a transaction printing device of the character described, means to print the lane number 1 of the particular lane monitored eveiy time a transaction is registered.

It is another object of this invention to provide, in a transaction printing device of the character described, means for printing the time to the nearest minute along with the usual information, such as forward and reverse axle counts, tariff classification number registered and lane number.

It is still another object of this invention to provide, in a transaction printing device of the character described, printed indication means to differentiate between automatically made hourly prints and individual transaction prints.

A further object of this invention is to provide a highly improved, compact and rugged device, of the character described, which shall be easy to operate, relatively inexpensive to manufacture, positive in action and which shall have wide application, yet be practical and eflicient to a high degree in use.

Other objects of this invention will in part be obvious and in part hereinafter pointed out.

This invention accordingly consists in features of construction, combinations of elements and arrangement of parts which will be exemplified in the construction hereinafter described and of which the scope of application will be indicated in the appended claims.

To this end, there is provided a printing hame.

mermechanism comprising a shaft 10.-having a hexagonal shoulder portion .H nearits externally threaded .end 12.: Said shaft is. mounted. in face. platel2 inan inwardly extendin positionas.

, by nut 13.

Rotatablyfl fitted on. saidshaft against said shoulderrportion. isa sleeve: 14,,held .in place. to prevent longitudinal movement by .a bushinglfib mounted on said shaftas byset screws 76,. There.

are-.mountedv on said. sleeve, .near each of its ends, two similar printing hammer assemblies.

(Figs-.6. and '7). Saidprinting hammercomprises a. U -shapedmember: 71 rotatablymounted.

At theclosedend-of said U-shapedmember there ishorizontallydisposed and mountedasbyrivets 83,,ahammermember 84 having agroove' 85 into.

which is cemented a rubber hammer. piece .86;

There is further provided, between .the arms of.i

Securely.v positioned against the rear of relay mountings. bar ll, opposite shouldered members l9 and in" Said pin is 1 said U-shaped member, a rod 81 adapted to hold one end of coil spring 88. The other end of said spring is connected under tension to a cotter pin 89 fixed in bracket I5 so that the printing hammers are normally held in a downwardly extending position. In the drawings, the printing hammers are shown in printing position There is also mounted on sleeve 14, as by set screw 30, at the end near the shoulder H a bushing 9i and its integrally connected crank member 92 having arms 93, 94 and 95. Arm 03 has affixed to it an inwardly extending pin 96 adapted to co-act with a paper-feed mechanism hereinafter described.

Arm 94 has a circular opening 91 to receive a connecting rod 98, partially shown, adapted to advance an inked ribbon R after each printing operation by means of a ribbon advance mechanism A, partially shown, such as, for example, disclosed in my patent for Electromagnetic Printing Counters, No. 2,115,410, issued April 26, 1938. The ribbon R is supported by ribbon guide rollers G so that the ribbon passes along the face of the printing wheels between the printing wheels and the paper.

Arm 95 is provided with a round opening 99 pivotally connected to a printing solenoid plunger I through a pivot link IOI connected therebetween as by pivot screws I02 and I03 held in place, respectively, by nuts I04 and I05.

Plunger I00 is associated with a solenoid mounted on bracket I5 and is adapted to be drawn down into said solenoid when it is electrically energized by a circuit hereinafter described.

From an inspection of the drawings it will now be evident that when said solenoid is energized the downward motion of its associated plunger I00 will, through connecting link I01 and crank arm 95, impart a clockwise rotational motion (Fig. l) to sleeve 14 against the tensional 7 force exerted by spring 88 attached to rod 81. Underlips 00, abutting against spacers 8| cannot move the printing hammers all the way for striking a print of the printing wheels against the paper but moves said printing hammers to a position just short of striking a print. The angular momentum thus imparted the hammers by the action of the solenoid in this manner further carries the hammers so that they strike so as to make a single, well-defined print and then fall to rest again against the lips 80, no matter how long thereafter I06 remains energized.

A paper feed mechanism is provided to advance the printing paper P each time a print is struck. Said mechanism (Figs. .9 and 10) comprises a shaft I01 havin a hexagonal shoulder portion I08 near its externally threaded end I00. Said shaft is mounted in face plate I2 in an inwardly extending position as by nut IIO. Rotatably fitted on said shaft and against said shoulder portion is a bell crank member III having arms H2 and H3. Arm H2 is equipped on its outer side with rotatably mounted pawl member II4, mounted as by screw H5 and having a toothed end H5 and an opposite end II1. Said opposite end is provided with a hole in which is fixed one end of a coil spring H8, the other end of said spring being fixed to an outwardly extending stud I I9 located at the end of arm I I2 so that pawl l I4 will be constrained by the force of said spring, against counter-clockwise motion with respect to arm II2 (Fig. 10).

Arm II3 has a slot II3a adapted to receive pin 90 on crank member 92 so that the paper feed mechanism is cooperatively connected to the printing mechanism.

There is also rotatably mounted on shaft I01 a bushing I20 having at its inward end and against bell crank member I I I a ratchet wheel I2I affixed thereto in position to act cooperatively with pawl II4. Next to said ratchet wheel there is, fixed on bushing I20, a grooved pulley wheel I22 adapted to drive a paper wind spool through the use of an interconnecting spring belt as is hereinafter described. Bushing I20 has cemented to it a rubber paper feed roller I23. Between the outer ends of rod 10 and rod I01 there is provided a strengthening link I24 rigidly interconnecting the ends of said rods through the use of screws I25 and I26 (shown in Fig. 2).

There is further provided, for cooperative action with ratchet wheel I2I, a pawl I21 rotatably mounted on a pin I28 fixed in face plate [2. Said pawl is held against said ratchet Wheel by the torsional force imparted by coil spring I29 circumjacently disposed said stud between face plate I2 and said pawl and having one end cone formed around the upper edge of said pawl and the other end fixed relative to said front plate as by screw I30.

It will now be evident from an inspection of the drawings, that when solenoid I06 is energized, makin a print, at the same time the cooperative movement of bell crank member III will, through the action of pawl II4, advance ratchet wheel I 2 I causing its paper advance bushing 20 and the attached paper roller I23 to rotate so as to frictionally drive the paper P into a new printing position. When the printing solenoid is thereafter de-energized, effecting a corresponding counter-clockwise motion of bell crank member III, printing roller I23 will be held against retrograde motion by the action of pawl I21 against the last advanced cooperative tooth on ratchet wheel I2 I.

Means is provided to hold a pressure roller against the paper in contact with the paper roller so that a greater frictional driving force will be imparted to the paper. To this end, there is Dro vided a shaft I3I (Fig. 11) having a hexagonal shoulder portion I32 near its externally threaded end. Said shaft is mounted in face plate I2 in an inwardly extending position as by a nut (not shown).

Rotatably mounted on said shaft are a pair of lever arms I33 and I34, one being positioned against the inner end of said shoulder portion and the other at the opposite end of said shaft. There is a spacer I35 rigidly fixed between said leve arms interconnecting them so that they are rotatable about said shaft only in unison. At the remote ends of said lever arms and rotatably mounted therebetween in bearing holes I33 and I31 is a pressure roller I 38.

Means is provided to hold said pressure roller against the paper and printing roller. To this end, there is circumjacently disposed on said shaft between a spring stop bushing I39, secure- 1y mounted on said shaft as by set screw I40, and a rotatably mounted pressure roller release lever I4I, a coil spring I42 having one end I43 fixed in a horizontal hole in said spring stop bushing and its other end I44 abutting against said spacer so that the pressure roller I38 is held effectively against the printing roller I23. Pressure roller release lever I4I, having an underlip I45 abuttin against the side of spacer I35 at a position adjacent spring end I44, is fixed to a bushing I46 rotatably mounted on shaft I3I. Said bushing and lever. arm I34 are-"held against? longitudinal movement on said shaft as byithe .underheadof a screwl tlimounted in the end .of saidshaft. Lever I4 I J is adapted to be manually rotatable against theitorsional force :of spring I42 away from papeproller I23 so that'a'new'roll of paper maybe more easily' threaded onthe transaction printer.

"Printingpaper roll unwind and take-up means is provided to store andautomatically advance theprinting paper each time a print is made.

To'this endthereis a paper spool-shaft i 38 having'apartly threaded reduceddiameter I49 at one end-forming. an annular shoulder I56 against which a circular paper' spool guide II isaxially mounted (Fig. 12). Said :shaft is rigidly fixed, in an inwardly extending position, to face plate I2 -as"by nut I52. Circumjacent said shaft, between the inner side of said face plate'and spool guide t5I,'-is a spacer bushing'l53. Said paper spool shaft is adapted to rotationally hold a spool of paper, having therefor end holding means comprising a circular spool guide I54 held on' the-end of saidshaft by a knurled machine nut I55.

There is provided friction means to prevent the paper spool: from unwinding freely under the influence :of angular momentum. To this end, there is provided a paper spool weight shaft I56 havinga hexagonal shoulder portion I5! near an externally threaded end. Said shaft is mounted in -face "plate I2 in an inwardly extending position as by a nut (notshown). Rotatably fitted onisaidishaft andiheld thereon as by spring clip I58 isza'fflat paper spool friction piece I53 looped atone 781141.170 fit on said shaft and Weighted at theotheriend as by weight piece E53 fixed thereon, the whole being adapted to gravitationally rest its lower weighted end against the paper on the paper-spool so as'to frictionally dampen any free unwinding of the paper.

Paper take-up mean is provided to automatically. rewind the printed paper. To this end, there is-provided a paper take-up shaft I6I having-a hexagonal shoulder portion I62 near its externally threaded end IE3. Said shaft is securely fixed, asby nut-I54, in face plate I2 in an inwardly extending position. Rotatably positioned onsaidpaper take-up shaft is a paper take-up spool I65 held thereon from endwise movement asby a screw I66 and a washer I67, held thereby, against the shoulder portion I58 of the countersunk end of said paper take-up spool (Fig. 13). The inward end of said paper takeup'spool has formed thereon a grooved pulley I BQadapted to co-act with the spring belt IT?) for rotational advancement of said paper takeup spool. Coaxially positioned on the paper take-up spool, against the side of pulley I69, is a circular paper edge guide disk Ill. The paper take-up spool is further provided with longitudinal diametrically opposite rectangular grooves I'll-and I73, both communicating with the outer end of the spool. Groove I72 extends substan (daily the length of said spool to the pulley I69. Groove I13 extends to about one-half the length of said spool. .There is further, for cooperative usewith said'paper take-up spool, a paper takeup'clampI'M (Fig. 14). Said clamp is a fiat piece'comprising handle part I75, shoulder portions I16 and Ill and horizontally extending groove fitting fingers I18 and I79, the whole being'adaptedtofit on and slide longitudinally on paperspool I65 and at the same time to hold V theend of the paper P in groove I12 by the clamping action of finger I18 therein. "The. shoulders I16 and Ill serve'as aguide so that the paper winds'squarely on the spool. Fingers I18v and I79, being deeper than the grooves they fit .into, project somewhat therefrom and when the rewound printed-paper is removed exert-a frictional force againstthe inside of the rolled paper so that it is easily removable upon'the withdrawal of the paper take-up clamp I'I-5.

There are further provided two horizontalpositioning paper guide shafts I and IBI,= one on either side of the printing wheel faces and in horizontal alignment therewith so that the; paper is fed horizontally past the, printing-wheel faces between them and'the inked ribbon R. Said guide shafts comprise arod I 82' undercut and threaded at oneend to be'bolted in faceplate I2 in. an inwardly extending position; The free ends of said rods are internally threaded to hold end :guide washers 183, as .by screws I84,'for lateral paper guidance.

The overall operation of thepaper advance, print and rewind mechanism is briefiy' stated as follows: An' unused paper roll is first placed on paper spool shaft Hi8 and threaded through the printer following a course, indicated by the dotted line inFig. 1 over paper guide shaft I80, between the printing wheels and the inked ribbon R,

under guide shaft IBI, over paper feed roller I23 (first having withdrawn pressure roller-I38by manual force on lever MI as hereinbeforeexplained), to paper take-up roller I65 whereon it is clamped as described using clamp I14. When a print is made, as hereinbefore-.-explained, the inked ribbon R is advanced, the paper mechanism advances the paper sufiiciently foranew print and at the same time, paper take-up shaft IBI coupled to paper feed roller I23 by the spring :In connection'with the electrical circuit for the printer and for the purpose hereinafter described, is a stepping switch vS associated with tarifflclassification number wheel 25 (Figs-15 and 16).

The movable contact arm of lane selector switch 65 is connected to the source of negative D. C. voltage supply, which is at ground potential.

It will now be evident that when the lane selector switch 66 isturned-to the particular position to monitor a given lane, lane I for example, the mechanically connected printing wheel 65 will correspondingly be turned to the position to printthe lane number I and at the same time an energization circuit will be completed to operatethe auxiliary relay-'20! associated with lane I. This' ci-rcuit can be seen to be from D. C.- to' the movable selector arm in switch 65, contact I, wire 235, through relay 201 to D. C.+. Thus the switches 201a, 2611); 2010 and 2Illd and'ZIl'Ie, 201 will each be closed, allowing the classification number auxiliary relays 2I0, 2H and 2I2- to be energized when their respective associated classification buttons CLI, GL2 and CLN in the keybox of lane 1 are depressed for a registration. Energization circuits are from ground, through lane I classification button CLI, wire 223, switch 281a, Zfi'lb, wire 232, through relay 2I0 to D. C.+ when button CLI in lane I is depressed; from ground through lane I classification button L2, wire 224, switch 2870, 201d, wire-233, through relay 2 to D. C.+ when but ton GL2 in lane I is depressed; and from ground, through lane I classification button CLN, wire 225, switch 201e, 2011, wire 234, through'relay 2I2 to D. C.+ when button CLN in lane I is depressed. Sincerelays 208 and 209 are de-energized when their corresponding lane number is not selected, the depression of' classification buttons in lanes other than the lane selected will have no effect on the transaction printer.

Switch armsZIIlb, 2! lb and 2I2b, respectively, of relays 2H1, 2I I and 2 I2 are connected in arallelto common wire 238 which also connects with switch arm 2I3b of'relay 2I3. Switch arm 2Ild is connected by, wire 23!! to fixed contact I on stepping switch S; switch arm 2| Id is connected by wire 240 to fixed contact 2 on said switch and switch arm 2I2d is connected by wire 2M to fixed contact N on said-switch. Switch arms 2I0a, 2'I0c, 2IIa, 2IIc, 2I2a and l2Ic, associated with relays 2H), 2H and 2I2 are all connected to D. C.+.

The movable arm associated with stepping switch SI is :connected by wire 242to one terminal of relay 2I3; The other. terminal of said relay is connectedin parallel with one terminal each of relays I06, 2I4, I25, 2I6.and 2I8 to thecommon wire 243 which connects to a terminalZMa of switch 244a, 2441): Terminal 244b-of said switch is connected'to'D; C. The other terminal of relay-2 l 8 isconnectedby wire-245 to its associated switch arm 2I8a. Switch arm 2I8b is connected by wire-246 to switch arm 2| 3a-associated with relay 2I3.

The operation of the stepping relay and switch can now be understood asfollows: Suppose lane I to be selected and classification button N of lane Idepressed. Relayz I 2 will then be energized and its switches IZIa, 2I2b and 21I2c; 212d will be.

closed; An energizing circuit will thus be completed to relay 218 from D. C.+ through closed switch 2I2a, 2I2b, wire 238, closed switch 2I"-a, 213b, wire 246,. closed-switch 2l8a, 2I8b. ire25,

' of solenoid 55.

to D. C.. However, sincerelay switch: 2I8a, 2 I 8b will beopened when itsrelay 2 I 8 is energized, thus again opening its energizing circuit, the relay will automatically be cyclically energized and de-energized for stepping or advancing its associated pawl and ratchet mechanism and the mechanically connected stepping switch SI, When the movable contact of stepping switch SI, reaches contact N, corresponding to the number of the classification button depressed, a circuit will be completed which, in effect, will open the energizing circuit to relay 2 I8 and thus stop further stepping. This circuit is traced from D. C.+, through switch 2I2c, 2I2d associated with relay 2I2, wire 2M, stepping switch contact N., the stepping switch contact arm, wire 242, relay 2I3, wire 243 and closed switch 244a, 2442) to D. C.. Relay 2I3, now being energized, has opened its switch 2I3a, 2I3b and broken the circuit to relay 2I8 preventing it from further stepping. The mechanically interconnected classification number printing wheel will now be in position to print the classification number N, corresponding to the classification number button depressed.

Switch arm 2l3c, is connected by wire 241 to I switch arm 2I'la' and also to the remaining terminal of relay 2I5; switch arm 2 I30. is connected by wire 248 to switch arm 214a; switch arm 2I3e is connected to D. C.+ and switch arm 2I3f is connected by wire 2:39 to the remaining terminal of relay 2% and also to switch arm IOBa.

Switch arms 2M?) and 2I id are connected to D. C.+. Switch arm 2I4c is connected by wire 253 to switch arm I661).

Switch arm 2I5a is connected to D. C.+ and switch arm 2I5b is connected by wire 25I to the remaining terminal of relay I06.

The remaining terminal of relay 216 is connected to D. C.+. Switch 2I6a is connected to one terminal of a source of A. C. supply voltage, ACI-I. Switch arm ZIGb-is connected by wire 252 to one terminal of relay 2 I I. The remaining terminal of relay 2 I7 is comiected by wire 253 to switch arm 22 lb. Switch arm 22 Ia is connected to the other terminal of the source of A. C. supply voltage, ACG.

Switch arm ZIlb is connected to D. C.+. Switch arm 2 I To is connected to the one terminal of a source of A. C. supply voltage'ACI-I. Switch arm 2 I Id is connected by wire 25d to one terminal The otherterminal of said solenoid is connected to the other terminal of the source of A. C. supply voltage, ACG.

The operation of the printing circuits is as follows: Normally, the relay 2 I2 is energized through the circuit from D. C., through wire 243, relay 2H3, normally closed switch 2I3e, 2I3 to D. C.+. After a registration button in a lane being monitored is depressed and stepping relay 2I8 has advancedits printing wheel to the corresponding number and is ready for a print to be taken, relay 2E3 becomes energized as hereinbefore explained. Eventhough the energization of relay 2 I3 will open switch 2 I36, 2 I3f, and thus open the above described energization circuit for relay 2M, said relay will remain energized temporarily through the new energization circuit from D. C. through wire 243, normally closed switch Idea, I861), wire25il, now closedswitch 2M0, 24 0, to D. C.+. Moreover, at the same time, an energization circuit is completed to the slower operating printing solenoid I36. This circuit is traced from D. C.- through wire 2&3, solenoid lflfl wire 25!,now closed switch 2I5a,

13 2 I517, to D. C.+, the auxiliary printing relay 2l5 now being temporarily energized by a circuit from D. C.- through relay I25, wire 241, closed switch 2130, 213d, wire 248, closed switch 2l4a, 2l4b to D. C.+.

Now that printing solenoid IE is energized, a print will be made and the transaction printer operated as hereinbefore described. However, as soon as a print is made, switch llifia, I062: associated with the printing solenoid will be opened, opening the hereinbefore described energization circuit through said switch for relay 2 [4, which, in turn, interrupts the above detailed energization circuits for auxiliary printing relay 2 l5 and printing solenoid 195. Since the switch 2 I do, 214d associated with relay 2M is now open, relay 214 being de-energized, the subsequent closure of switch 106a, I061; cannot make an energizing circuit for relay 2M, therefore, switch 2l4a, 2l4b will remain open and another printing operation is not effected.

Since the operation of the stepping relay and the other relays is rapid, the printing operation takes place practically instantly upon the pressing of a classification button. After a print is made and the classification button switch is thereafter opened, relay 2l3 will be de-energized, allowing relay 2 l4 again to become energized through switch 2 l3e, 2 l3 But, at the same time, switch 2 I30, 213d is opened, interrupting the circuit to auxiliary printing relay 2 l5 and thus preventing extra prints from being made. The printing circuits are now in readiness for another cycle of operation initiated by the depression of the same tariff classification number button or another tariff classification number button in the lane being monitored.

Provision is made for the printer to automatically make prints on the hour. As hereinbefore described, the time relay 22! is adapted to momentarily close switch 22m, 2212; on the hour. When this is done, an energization circuit for relay 2ll is completed from ACG through switch 22la, 22lb wire 253, relay 2H, wire 252, closed. switch 2l6a, 2l6b to ACH; the relay 2ll6 being closed whenever the transaction printer is in use because of its energization by the circuit from D. C. through apparatus switch 244a, 244b, wire 243, relay 2|6 to D. C.+. Relay 211, being energized, will, through its associated switch 2l'ic, 2l'ld, close an energization circuit for T printing solenoid 55, the circuit being from ACG, through solenoid 55, wire 254, switch 2110, 211d to ACH. At the same time, an energization circuit will be completed to auxiliary printing relay 2l5, closing its switch and thus effecting the making of a print. As hereinbefore described, the hourly print will be distinguished from transaction prints by the printing, along with the other information, of the letter T.

Forward and reverse treadle count relays 219 and 22B are energized by the actuation of the treadle contacts associated with the treadle of the lane selected for monitoring through the use of a treadle actuated relay circuit such as is disclosed in applicant's Patent No. 2,313,627, issued March 9, 1943, titled: Treadle Controlled Toll Checking System.

The selecting circuit for accomplishing this is a duplication of the selection of the keybox classification button circuits and may be accom plished by the use of the additional switches 201g, 'lh; 297i, 201i; 2017c, 2011; 251m, 2011i; 2589, 298k, etc. on the lane selector relays 201, 208 and 299; as shown in Fig. 22. Thus, when a particular lane is selected to be monitored, its associated treadle will be connected to the transaction printer through the treadle actuated relay circuit to actuate the forward and reverse axle counter relays H9 and 220. It should be noted that by the expedient of employing a separate treadle actuated relay circuit, rather than switching to the output of the particular treadle relay circuit in the individual lane registers, a check can be made of the operation of the individual lane treadle relay circuits; and, should an individual lane treadle relay circuit fail, the transaction printer could be used temporarily to make a record of the treadle count for that lane.

Fig. 22 shows a modification of the invention providing for remote selection of the lane to be monitored through the use of an electrically connected lane selector switch panel 255 having a plurality of double pole single throw toggle switches Ll, L2, LN, one for each lane in the system (Figs. 18 and 22). Said switch panel is interconnected in the circuit with a stepping switch S2, similar in construction to SI, an auxiliary relay 251 and a stepping relay 258, as hereinafter described.

Fig. 21 shows the mechanical details of the modification of the transaction printer (as shown in Fig. 3) providing for remote switching. Relay mounting bar l! is extended to provide for the mounting of stepping relay 258 in an additional shoulder member l9 provided with a pair of depending shoulders 20?) and 21b. Fixed between the lower ends of said shoulders is a horizontal shaft 259 aligned with shafts 22, 23 and 24. The lane number printing wheel 50 in this instance is fixed on shaft 259 at the outer side of shoulder 20b. Pawl swing 260 is actuated by the stepping relay 258 when pulsed so as to rotatively advance shaft 259 and printing wheel 60. A stepping switch S2, similar in construction to SI hereinbefore described, is similarly mounted to the outer side of depending shoulder 2 II) for cooperative switching upon the rotative advancement of shaft 259. There is further the rotor 65a of switch 65 fixed to said shaft, its stator 65b being cooperatively mounted therewith as by mounting bracket 26! afiixed to mounting bar l1.

Referring now to Fig. 22, relay 251 is provided with a pair of switch contacts 251a, 25') normally closed but adapted to be opened when said relay is energized. Relay 258 is likewise provided with a pair of switch contacts 258a, 258b, normally closed but adapted to be opened when said relay is energized. Each of said relays has one of its energization terminals connected to the source of voltage supply D. C.

The remaining energization terminal of relay 251 is connected by wire 262 to the rotor of stepping switch S2. The remaining energization terminal of relay 258 is connected to its switch contact arm 258a. The switch arms 251D and 25% of said relays are interconnected by wire 263. Switch contact arm 251a is connected as by wire 264 to wire 243 which is connected in common with one fixed pole each of the double pole, single throw switches Ll, L2, LN in the lane selector switch panel 256. The remaining fixed poles of said switches are connected by wires 265, 256 and 261 respectively to the stator contacts I, 2 and N of stepping switch S2. All the opposite switch arm poles of switches Ll, L2 and LN are connected in common to D. C.

The operation of the remote lane selector in connection with the stepping switch S2 is similar to the operation of stepping switch SI associated 17 lays to pulse said relays so as to count vehicles moving in said lane over said treadle in forward and reverse directions respectively, and means to print the count on said forward and reverse counter relay number wheels concurrently with the printing of said classification indicium.
